.The invention relates to machines for bonding and upsetting metals, andhas for its object to provide means whereby either of the operations maybe performed separately or simultaneously, as desired.

The invention has for its further object to increase the scope of'thesemachines, whereby they are adapted to bend or upset or perform bothoperations on metals having various forms in cross-section-such asround, semi- I cylindrical, square, oval, or L, T, or double- Tshaped-and to produce a compact and efficient machine that is readilyoperated.

To tgiese ends the'invention consists in the combination, with astationary carrier, a rotatable carrier, and sector-shaped shaping-'blocks secured thereto, of gripping-levers for securing the metal to beoperated upon to said blocks, substantially as hereinafter fullydescribed.

The invention further consists in the combination, with a rotatablecarrier, a carrier having a rectilinear movement toward and from saidrotatable carrier, and sector-shaped shaping-blocks secured thereto, ofgrippinglevers for securing the metal to be operated upon to saidblocks, substantially as hereinafter fully described.

The invention further consists in the'combination, with a rotatablecarrier, a carrier having a rectilinear. movement toward and from saidrotatable carrier, sector-shaped shaping blocks secured thereto,.andgrippinglevers for securing the material to the blocks, of lockingdevices whereby either of the carriers may be locked against movement,substantially as hereinafter fully described.

The machine is composed, essentially, of two working sections orcarriers,A B. Of these one may be stationary and the other movable, as

in Figs. 1 and 2, or one of said carriers may have a rotary and theother a rectilinear mo tion, as in Figs. 3 to 7.

As shown in, Fig. 2, the upper portion or head of the carriers A and Bhas the form of a sector, the carrier A being pivoted to the carrier Bby means of a central pivot, I, and the carrier B is securely fastenedto a supporting-blg ck,B gof,wood or other material; or said carrier Bor the'block B may be const-ructed so as to be secured in a bench orother vise when used for bending small articles of metal. 1

A and B are two wedge or sector shaped shaping-blocks secured,respectively, to the carriers A and B, the opposite vertical faces ofwhich blocks are roughened or serrated or provided with teeth.

a a and b b are holes or recesses formed, respectively,in the headsofthe carriers A and B for the reception of gripping-levers O,betweenwhich and the'bloeks A and B the metal to be bent or upset is securelyheld, as shown in Fig. 2. The holes or recesses a and b are formed atdifferent distances from the axis of rotation of the carrier A, and upona circle concentric therewith, so as to accommodate bars or beams ofmetal of varying diameter, as will be readilyunderstood. The carrier Ais also provided with sockets or holes ain the periphery of the headthereof for the reception of an operating-lever, If, by means of whichsaid carrier is rotated either toward the right or left on the sectionB.

The operation of this machine is as follows:

The carrier A is rotated until the shapingbloeks A B are brought to aposition with one of their serrated faces on the same diametral line.The bar of iron to be bent is then clamped by means of thegripping-levers to said bloeks,and the carrier A rotated by means of thelever L to bend the bar, as shown in Fig. 2. If it is desired to upsetthe end of a bar or piece of metal, it is clamped to one of the blockswith its end that is to be upsetlying in the space between the two blocls,and an upsetting-block is clamped to the other shapingbloek, so thatwhen the carrier A is rotated, the upsetting-block, clamped to theshaping-block A thereof, will upset the end of the bar, as hereinafterreferred to. In this operation the upsetting-block is preferably clampedto the block A of the rotatable carrier A,and the bar of iron to beupset to the block B of section 13, though this is not absolutelynecessary.

Although two gri pping-levers are preferably used, this is notabsolutely necessary, as one such lever will answer the purpose,especially when the machine is constructed for bending light rods,rails, &cl

In case there should be difficulty in rcmoving the bent bar from themachine-or,in other words, in disengaging the grippinglevers therefromby reason of their serrated surfaces and those of the blocks A B sinkingtoo deep into the metal-the block A or that B, or both, are connectedwith their respective section by means of a pin and key, so as toreadily detach the same therefrom; and to prevent the accidentaldisplacement of the blocks on their sections, they may be seated inrecesses (1 N, Fig. (i.

To increase the scope of the machine as well as its efficiency, it maybe constructed as shown in Figs. 3 to 7.

E E is the frame, the right-hand base portion E of which is bowl-shapedand has a hearing for the hinge pintle or pivot P and an annular flange,0, provided with a series of holes, 0, and also a bearing for one end ofan inclined shaft, G, whose other end has its hearing in a cross-pieceat the left end of the frame of the machine. This shaft carries at thelower end a bevel-pinion, g, and at its upper end a segmentalbevel-wheel, 9, that meshes with a bevel-pinion, g ,on the short shaftS, that also carries a fly-wheel, F, provided with a handle,

f, for rotating the same. The frame E has two arms, E, that project overthe base E, said arms being perforated for the reception of thepivot-shaft P, by means of which the carrier A is hinged or pivoted tosaid frame-arms. The carrier B in this construction of the machine isslotted and capable of sliding toward and from the carrier A on the armsE of the frame E, from which said carrier 13 is also sup ported. On thelower end of the pivot-shaft l is mounted a bevel-wheel, H, that mesheswith the pinion g on shaft G, and from which pinion said wheel isrotated. In the upper face the wheel H has a series of holes, h,corresponding in number with the number of holes a in the base-flange eof frame E. The carriers A B are here also provided with shaping-blocksA B and grippinglevers O, .forsecuring the material to be operated uponto said blocks A B, and a a and Z) Z) are theholes in the heads of thecarriers for the reception of the pins or pivots of the saidgripping-le-- vers, in which holes said'pivots fit loosely, the leversbeing shifted from one side of the blocks to the other, according to theside operated with, or when both sides of the blocks are alternatelyused for bending or upsetting, or both, a bar being applied to one sideof the blocks while the bar previously operated upon by the oppositefaces of the blocks is being removed.

M is an arm projecting from the rotatable section A. It has four holes,or m and m m. The holes in m register with the holes h in the upper faceof the wheel H, and the holes at m register with the holesc in theflangee of the base E of frame E, for purposes presently explained.

A rectilinear movement is imparted to the carrier B of the machine bythe following instrninentalities: K is a lever fnlcrnmed at 7. upon theupper arm, E of the frame E, and said lever is pivoted to the upper endof carrier B, the piv0t-pin 6" having the necessary play in a slot, 7:,of lever K. The said lever has a slot-ted projection, It", in the slotof which plays a pivot-pin, Z, at one end of a lever, L, that isfnlerumed at 12 upon the lower arm, E of frame E, the opposite end ofsaid lever L being pivoted to the lower end of carrier 13 at I). Alover, I, pivoted upon the pivotshaft P, has a number of holes, 1', andtwo holes, t i. The hole '5 registers with the holes or sockets h in theface of the wheel H, and the hole t" with those 0 in the flange 6 of thebase E of frame E. The lover I is connected with the lower end of thelever K by means ofa link, J, Figs. 3 and 7.

It is obvious that when the lever I is locked by means of an eyebolt orpin, 1, to the wheel H, and that when said wheel is rotated in thedirection of the arrow a", Figs. 4, 6, and 7, the lower end of lever Kwill be thrown outward or toward the left, thus moving inwardly ortoward the right at its upper end above the fulcrum 70. At the same timethe end of lever L, above its fulcrum I, is also carried outward ortoward the left, while the end below the fulcrum Z is carried inward ortoward the right,

thereby moving the section B in a rectilinear direction toward thecarrier A.

When it is desired to simply bend a bar of metal without upsetting thesame, the arm M of the rotatable carrier is connected with the wheel Hby means of a locking bolt or pin, M, Fig. 7, and it'is evident that ifsaid wheel is rotated by the mechanism described the section A willrotate therewith,while the section Bwill remain stationary, the lever Ibeing disconnected from wheel H, and connected with the base-flange e offrame E'by means of thelocking bolt or pin I. When, on the other hand,it is desired to upset a bar of metal, then the lever I is rigidlyconnected with the wheel H,and the arm M with the base-flangee offrameE. Finally, if it is desired to bend andupset a bar of metal, then thelever I and arm M are both locked to the wheel H, asjwill be readilyunderstood. By means of the holes e inthe flange e'of the base E and theholes h in the upper face of the wheel H, any desired position may begiven to the rotatable carrier A relatively to the sliding carrier B.The amplitude of the rectilinear movement of the carrier B may be variedwithin certain limits, for which purpose the lever I is provided with anumber of holes, 43, as above stated, .to vary the point of connectionbetween it and the" arm or link J, that connects levers H I, and therebyvary the amplitude of the throw of said lever, as will be readilyunderstood. It will also be seen that the lever I may be shifted fromone side of the machine to the other, as may be found most convenient,and, if desired, the arm M, instead of forming an integral part with thesection B, may be made of aseparate partand keyed to the pivotshaftP ofthe carrier B, the wheel H being in this case loosely mounted on saidpivot, and means provided such as a clutch-coupling for connecting thewheelwith the shaft. The arm M, for instance, may also be connected withthe pivotshaft by a feather or spline, so as to cause it to rotatetherewith, but leave it free to slide vertically thereon, and may beprovided with one half of a clutch-coupling, the other half of which maybe formed with or secured to the wheel H, as will be readily understood.

These machines are adapted to impart a variety of forms to bars or beamsof metal by means of the shaping blocks and auxiliary blocks orblocking-bars.

In Fig. 8 we have shown .the operation of forming a counter-bend in abar of iron, the block A of the movable carrier A being removed and ablocking'bar, a, employed in its stead, in conjunction with a secondbar, a, the end of which, in conjunction with the block B, forms thecounter-bend, as shown. It is obvious that the extent of the bend willdepend upon the width of the end of bara, that abuts against the bar tobe bent.

In Figs. 9 and. '10 we have illustrated the means for forming a crank ina bar or rod of metal by means of blocking-bars a a, one of the latterbeing placed under the bar to be bent whenever the thickness thereof isless than the height of the shaping-block.

In Fig. 11 we have illustrated the means for upsetting a bar of metaland imparting to the upset end. thereof any desired form by means ofupsetting-blocks a, the upsetting end 0t which has the form intended tobe given to the upset end of thebar. In'this case both blocks A and Bare brought into use.

In Fig. 12 we have shown the manner of upsetting a bar of iron so as toproduce an enlargement at any point between the two ends thereof, and,finally, in Fig. 13 we have illus trated a few of the various forms thatmay be imparted to metal bars or beams by means of the improved machine.

If desired, shaping-blocks A B of-different thickness may be employed,according to the thickness of the material opera-ted upon, instead ofemploying filling-out pieces. The various blocking-bars and blocks a a,&c., are detachable from the heads of carriers A B, each having one ormore pins or lugs adapted to fit into the holes a and 1), formed in saidsections.

In bending angle-iron this is efiectedby applying the power either uponthe web or the wing thereof, the same being done when bending T, U, ordouble-T iron, and suitable filling-out pieces may be employed topreventwrinkling in the web or wings.

Having thus described our said invention and how the same is to beperformed, we claim as our invention and desire to secure by Let.- tersPatent- 1.
